,My invention relates to an innum'eznent in overhend trove-.ling cranes, wherein two trolleys are mounted totroy-el on the same shin/ying them coupled together, with pinions on 'the hoist drums interineshing, and 'l 1 ig. is View in side elevation ol saune.

li. and Z oooh represents s section oi n trolley, both ol which nre .mounted to travel on the trooli wey oi nu oxgerhcnd traveling Grone. lil-eeh trolley provided with the usuel motor ind gearing (not shown) for propelling it lonvitndiintliy on the bridge rind zilso Vith a hoist motor (nor-shown) l'or actuating its hoist drum. Y

"the hoist drums 3 and el nre ninna-ned in their trolleys, the hoist drum 3 being provided :it one end with u large toothed wheel 5 which meshes with pinion o zictuetod hy gearing l'roin its hoist motor, end the hoist drinn is provided with similar geen' 5 driven hy pinion G, :ind is also provided on its opposite. end' with n large toothed wheel 7 which hitter adopted, when the two trolleys :rre coupled up, to mesh with pinion 5 ou. drinn 3 ond roliste in unison therewith.

fl`he two trolleys l :ind 2 sire coupled together hy the hars fi, etre-h oi' which is proyided et ends with openings to receive .oi the drum shafts. Enr-.li shalt j ted :it one end und iiirorided with en 'seribed,`but,

end llxinge l) which hitter limits the lateral sliding movement olI its har. The elongotd end B" ol' one slnil't located opposite thel short end of the other shaft, und by sliding the coupling hors 8 laterally, or in the direction. of the length of the shafts, they will be disconnected from the shorter ends, und may then be turned back and rest on its trolley until signin needed for coupling the two trolleys. Each trolley therefore carries one connected from the shaft of the other trolley 'the two trolleys nre free to be used independently of euch other. Each bar is provided with n removable or adjustable takeup pluto l() secured thereto, sind b r means of which all weer on the lun' or she ts may he compensated for, :ind the two trolleys. be held in proper relative positions without any independent longitudinal Inoizinent. By this arrangement the hoist motors on the two trolleys con be utilized for lifting a. single load, suspended from. the chains of one or hoth hoist drums, when the trolleys. are coupled, and when the letter are uncouplcd eatehtroiley and its hoist drum can be used independently ot' the other.

.it is' evident that mrinyl slight changes might be 'resorted to in the relative arrangement of parts shown Aand described without depfntiner from the spirit and scope of my invention hence I would have it understood that l do not wish to con'line myself to thc exact construction of parts shown ind de- Hoving fully described my invention what I claim ns new end desire to secure by Letters-Patent, is

1.. The combination with two independent trolleys each provided with n. hoist drum sind gearing i'orrotsting oooh drum, of melius for couplingY the trolleys whereby they nre cinised to .travel in unison und ineens for couplingl the hoist gears of sind trolleys.
